Otiorhynchus rhacusensis is a species in the weevil family (Curculionidae).
Otiorhynchus rhacusensis can reach a length of about 15 mm. The basic color of the body is whitish, with flat reddish granules on the pronotum and elytrae and reddish femurs.
This species is present in Bosnia and Herzegovina and Sicily.
Weevils are beetles belonging to the superfamily Curculionoidea, known for their elongated snouts. They are usually small, less than 6 mm in length, and herbivorous. Approximately 97,000 species of weevils are known. They belong to several families, with most of them in the family Curculionidae. It also includes bark beetles, which while morphologically dissimilar to other weevils in lacking the distinctive snout, is a subfamily of Curculionidae. Some other beetles, although not closely related, bear the name "weevil", such as the biscuit weevil, which belongs to the family Ptinidae.
Black vine weevil is an insect native to Europe but common in North America as well. It is a pest of many garden plants.
Otiorhynchus is a large genus of weevils in the family Curculionidae. Many species of the genus, particularly the black vine weevil and the strawberry root weevil, are important pests, both as larvae and as adults. Larvae feed on plant roots. Adults are flightless with fused elytra and feed at night on plant foliage. In many species of the genus at least some races are polyploid and parthenogenetic, while the rest of the races and species are diploid and bisexual. Otiorhynchus weevils, particularly O. scaber, have been a popular subject for studies of the evolution of parthenogenesis. The genus is native to the Palearctic region. However, sixteen species were inadvertently introduced to North America and have become widespread there.
The Entiminae are a large subfamily in the weevil family Curculionidae, containing most of the short-nosed weevils, including such genera as Entimus, Otiorhynchus, Phyllobius, Sitona, and Pachyrrhynchus. In comparison with their stunning diversity, only a few of these weevils are notorious pests of major economic importance. Entimines are commonly encountered in the field, including urban environments, and abundant in entomological collections.
Otiorhynchus ovatus, the strawberry root weevil, is one of the many species in the weevil family (Curculionidae), occurring across Canada and the northern United States. The species was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae. Its name comes from its affinity for strawberry plants, which form a large part of its diet. They are, however, known to feed on other plants as well. Occasionally the larvae cause serious damage to seedlings and young transplants in plantations and nurseries. It is known to be one of the major pests threatening sub-tropical strawberry farming.
Otiorhynchus morio is one of the many species in the weevil family (Curculionidae). It was first described by German entomologist Ernst Friedrich Germar in 1824.
Otiorhynchus cribricollis is one of the many species in the weevil family (Curculionidae). It is native to the Mediterranean and a pest of apple orchards and vineyards in Western Australia.
Otiorhynchus armadillo is a species of broad-nosed weevil belonging to the family Curculionidae, subfamily Entiminae.
Copelatus taprobanicus is a species of diving beetle endemic to Sri Lanka. It is part of the genus Copelatus in the subfamily Copelatinae of the family Dytiscidae. It was described by Wewalka & Vazirani in 1985.
Otiorhynchus gemmatus is a species in the weevil family (Curculionidae).
Otiorhynchus meridionalis, the lilac root weevil, is a species of broad-nosed weevil in the family Curculionidae. It is found in North America. Lilac root wevils are shiny, brownish-black beetles, about 0.25 inches (0.6 cm) with long snout (rostrum) and geniculate (elbowed) antennae. They are common landscape pests, feeding on lilac, euonymous and peonies.
Otiorhynchus crataegi, the privet weevil, is a species of broad-nosed weevil in the beetle family Curculionidae.
Otiorhynchus ligustici, known generally as the alfalfa snout beetle or lovage weevil, is a species of broad-nosed weevil in the family Curculionidae. It is found in North America and Europe.
Otiorhynchus raucus is a species of broad-nosed weevil in the beetle family Curculionidae. It is found in North America.
Otiorhynchus ligneus is a species of broad-nosed weevil in the beetle family Curculionidae. It is found in North America.
Otiorhynchus porcatus is a species of broad-nosed weevil in the beetle family Curculionidae. It is found in North America.
Otiorhynchus rugosostriatus, known generally as the rough strawberry root weevil or rough strawberry weevil, is a species of broad-nosed weevil in the beetle family Curculionidae. It is found in North America.
Otiorhynchus carinatopunctatus is a species of broad-nosed weevil in the beetle family Curculionidae. It is native to Europe and introduced in North America.
